Advantages of distributed database over traditional centralized database

In the era of big data, in the face of more and more massive data, the disadvantages of traditional centralized database are increasingly apparent. Compared with traditional centralized database, distributed database has the following advantages.

● Higher data access speed: In order to ensure the high reliability of data, distributed databases often adopt the backup strategy to achieve fault tolerance, so when reading data, clients can read data from multiple.

The backup server reads at the same time, which improves the data access speed.

● Stronger scalability: Distributed databases can achieve linear expansion of storage capacity by adding storage nodes, while the scalability of centralized databases is very limited.

● Higher concurrent access: Distributed databases can provide users with higher concurrent access than centralized databases because they use multiple hosts to form storage clusters.
